.citizen of the United States, residing at Pittsl 4 burg, in the county of Alleghenyand State of Pennsylvania, have invented a newand useful Improvement in Chaplets for' Supporting Cores in Molds, of specification.

- My invention relates generally to -.the ',art of forming .metalcastingg and particularlyto the means employed for supporting and.y

. makingcastings.

'.. separation of cores in m'olds, 'dilferent sizesv the thickness of the casting to be made, and' consequently the width-of the spaces-between 'and around thezcor'es'.' It is well known that there is more'or less variation inthe forms .v anddimensions of coresbrought about by thev l. asA

. sition by any small fragment' of metal or other separating the cores of molds employed for Heretofore, it has .been the practice to. employ chaplets of invariable lengths for the of chaplets'being provided in accordance with baking operation. Such variation may be due to either shrinking o r swelling; but whatever its nature it is apt to be'uncertain, and unL equal at different poi-nts. It'has beehthe practice generally, therefore, among melders where the ehaplets at hand were too short, as

would'usually be the case on account -e'f I the shrinkage of the cores, to wedgefthem in po'- substance that might be at hand,- and'such wedging has been unreliable, insecure, and generally unsatisfactory. In order to overlas.

come the difficulties that have been experiv enced `in the direction above indicated, I have devised an adjustable chaplet that is adapted for. satisfactory'use in spaces which may-vary within considerable limits. The device is villustrated in the drawings, in which- Figure 1 is a view,v partially in side eleva-` tioni and .partially in section, of one form of] my invention; and Fig. 2 is a similar View of l'a modification. Fig. 3'is a sectional'view of a-mold and two cores separated bychaplets f constructed in accordance .with my invention.

which the following `is af In the form` shown in Eig-1 the device 4 comprises two heads 1, the outer faces of4 mounted lupon a' screw-threaded stem 3, so

that their outer faces are substantially' in par- -allel planes.- The screw-threaded engage ment between the heads and the stem 3 will preferably be free'tting, sogthat the heads s "may lie-turned easily on the stem. i vThe chaplet 4.@ (shown in Fig. 2) comprises two heads la like the heads 1, (shown 'in Fig.

1,) `eii'cept that each of them is provided with. a central cylindrical-opening 2 of slightlygreater-diameter than-the" stem` 3. In order 'to varyv the length of this form of chaplet, I

provide two nuts 5 to serve as adjustable stops .for the headsla. I' A y 1 vIt will be seen that either form vof chapletu 'm\ay be placedl between the cores 6and-be.. twe thefsides 'ofthe cores and the adj-a,`

cent walls'oflfthfil mold @as indicated in Fig. l f 70,

3; andji'fthesel' spaces are'not 'equal either 4or"b )tl1".of the heads may be adjusted on the screw, so as to make the elizqiletsv of exactly the right length to properly support the cores and hold them in exactly the position towhich they are adjusted. I claim as my invention-'- 1.A A chaplet for separating and supporting cores in molds, comprising a stem and two heads which have. outer faces'ofl relatively -large area and are adjustabl'y mounted upon the ends ofthe stem.

2. .-A chaplet for separating and supporting .cores in molds, comprising a screw-threaded stem and two internally-screw-threadedheads which have outer faces of relatively large area and are mounted'upon the ends of the stem.

lIn testimony whereof I have hereunto sub'- A' scribed my name this 8th day o'f October, 1900.v
